Photobiomodulation therapy for chronic knee pain in obese patients in pre-rehabilitation for bariatric surgery: randomised, placebo-controlled, double-blinded, clinical trial protocol.

INTRODUCTION: Obesity has become a worldwide public health problem and is directly linked to loss of quality of life, complications and comorbidities. One of them is chronic pain, especially in the knees, which increases significantly and proportionally with weight gain. In patients with severe obesity, with indication for bariatric surgery, the presence of chronic pain disables and often prevents their participation in a pre-surgical rehabilitation programme. As an analgesic therapy, photobiomodulation (PBM) has been studied with safety, efficacy, well-tolerated used and low costs. Thus, this study aims to evaluate the use of PBM for the treatment of chronic knee pain in obese patients undergoing a pre-surgical rehabilitation programme for bariatric surgery. METHODS AND ANALYSES: This is a double-blinded, randomised, placebo-controlled clinical, superiority, trial protocol. The PBM will be applied in bilateral knees and lumbar paraspinal points levels referring to the roots of innervation of the knee. The outcomes evaluated will be pain intensity, functionality, quality of life and clinical signs of neurological sensitization of chronic knee pain pathways. ETHICS AND DISSEMINATION: This protocol has already been approved by the Comitê de Ética em Pesquisa do Hospital das Clínicas da Universidade Federal de Goiás/EBSERH-Ethics Committee and it is following SPIRIT guidelines. The results will be statistically analysed and subsequently published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: Clinical Trials Platform (https://clinicaltrials.gov/) with the number NCT05816798.

Comparison of home-based rehabilitation and a centre-based exercise in terms of functional capacity, muscle oxygenation and quality of life in people with peripheral arterial disease: a protocol for a randomised controlled trial.

INTRODUCTION: Peripheral arterial disease (PAD) is increasingly prevalent, and supervised physical exercise programmes are recommended as the first-line treatment. However, these programmes are underused. Alternative delivery models may be able to expand treatment coverage. The objective of this study was to compare a home-based exercise programme (HBEP) and a centre-based exercise (CBE) in terms of their effects on functional capacity, peripheral muscle oxygenation and quality of life in individuals with PAD. METHODS AND ANALYSIS: This single-blind, parallel randomised clinical trial will consist of two groups: HBEP and CBE. A qualitative analysis will be carried out to investigate acceptability and satisfaction. The primary outcome will be functional capacity, assessed by the incremental shuttle walk test. Secondary outcomes will include functional capacity, assessed by a treadmill walking test; peripheral muscle oxygenation and quality of life; and self-reported functional impairment, risk factors, morbidity, level of physical activity, adherence, acceptability and satisfaction. The intervention protocols will consist of 12 weeks of intermittent walking until claudication symptoms, three times a week. Participants randomly assigned to the CBE group will participate in supervised face-to-face sessions. The HBEP group will perform exercises at home with remote supervision, monitored by a pedometer and heart rate monitor, and subjective perception of effort during each session will be recorded by participants in a training diary; follow-up will be conducted by telephone calls. Statistical analyses will follow the intention-to-treat principle. Participants allocated to the HBEP group will be interviewed about their experience of remote treatment using a qualitative approach. ETHICS AND DISSEMINATION: Ethics approval was obtained from the Ethics Committee of the Universidade Federal de Minas Gerais. The results will be disseminated in a peer-reviewed journal and presented at international congresses. This research has the potential to improve the care of people with PAD because if home-based rehabilitation demonstrates effectiveness, it could be considered an alternative or support resource to the usual centre-based treatment models, expanding access, coverage and participation in vascular physiotherapy TRIAL REGISTRATION: https://ensaiosclinicos.gov.br/rg/RBR-97vy9n7 on 14 April 2022.

Predictive value of functional disability scales among stroke survivors: A long-term mortality evaluation in a Brazilian stroke cohort.

OBJECTIVE: To assess the influence of two functional scales- Modified Rankin Scale (m-RS) and Modified Katz Index (m-Katz Index) on long-term mortality in a stroke cohort. MATERIAL AND METHODS: Among 760 stroke survivors (median age: 66 (IQR:56-75), 56.4 % women) m-Katz Index and m-RS scales applied at 1 and 6 months after stroke, were investigated in relation to 12-years of all-cause mortality. Kaplan-Meier survival curves were computed, and time-varying covariate Cox regression models were fitted to calculate hazard ratios (HRs) with 95 % confidence intervals (CIs) in all sample and by sex. The prognostic ability of the fitted models was computed for each model by six different measures. RESULTS: After 12 years of follow-up (median survival time: 7.3 years), 311 participants died. Overall survival curves show lower survival rates among those with the highest levels of disability/dependence (all log-rank p-values <0.0001). These findings were confirmed in all regression models for both sexes, particularly in men who had higher levels of dependence on Activities of Daily Living (ADLs) by m-Katz Index and severe disability by m-RS and presented the highest HR of dying (HR: 3.34 (95 %CI: 2.27-4.92) and HR: 4.94 (95 % CI: 3.15-7.75), respectively). CONCLUSIONS: Both the m-Katz Index and the m-RS scale were good predictors of long-term mortality, which is of importance for guiding the functional rehabilitation of stroke patients. Besides, high levels of disability and dependence were implicated with high mortality risks, regardless of sex.

Ai based motion analysis software for sport and physical therapy assessment / Software de análisis de movimiento basado en ia para la evaluación del deporte y la fisioterapia / Software de análise de movimento baseado em ia para avaliação de esporte e fisioterapia

ABSTRACT Introduction: As the World Health Organization declared the novel coronavirus as a pandemic in March 2020, physical therapy is more difficult to execute, and social distancing is mandatory in the healthcare sector. Objective: In physical therapy, an online video analysis software that provides real-time graphic and numerical information about the patient's movement executions without direct personal contact would mean a significant improvement in eHealth treatment. Methods: We have developed a software layer on top of OpenPose human body position estimation software that can extract the time series of angles of arbitrary body parts using the output coordinates from OpenPose processing the data recorded by two cameras simultaneously. To validate the procedure of determining the joint angles using the Openpose software we have used the Kinovea software. Results: The comparison of the determined maximal knee angle in our and the Kinovea software, which is widely used in biomechanical measurements, was not significantly different (2.03±1.06°, p<0.05) Conclusion: This indicates, that the developed software can calculate the appropriate joint angles with the accuracy that physiotherapy treatments require. As, to our knowledge no such software yet exists, with the help of this software development, therapists could control and correct the exercises in real-time, and also from a distance, and physical therapy effectiveness could be increased. Level of Evidence II; Experimental, comparative.

Latin American Cerebral Palsy Register (LATAM-CPR): study protocol to develop a collaborative register with surveillance of children with cerebral palsy in Latin American countries.

INTRODUCTION: Cerebral palsy (CP) is one of the leading causes of childhood disability globally with a high burden in low-income and middle-income countries (LMICs). Preliminary findings from the global LMIC CP Register (GLM CPR) suggest that the majority of CP in LMICs are due to potentially preventable causes. Such data are lacking in the Latin American region. Generating comparable epidemiological data on CP from this region could enable translational research and services towards early diagnosis and early intervention. We aim to establish a Latin American multicountry network and online data repository of CP called Latin American Cerebral Palsy Register (LATAM-CPR). METHODS AND ANALYSIS: The LATAM-CPR will be modelled after the GLM CPR and will support new and emerging Latin American CP registers following a harmonised protocol adapted from the GLM CPR and piloted in Argentina (ie, Argentine Register of Cerebral Palsy). Both population-based and institution-based surveillance mechanisms will be adopted for registration of children with CP aged less than 18 years to the participating CP registers. The data collection form of the LATAM-CPR will include risk factors, clinical profile, rehabilitation, socioeconomical status of children with CP. Descriptive data on the epidemiology of CP from each participating country will be reported, country-specific and regional data will be compared. ETHICS AND DISSEMINATION: Individual CP registers have applied ethics approval from respective national human research ethics committees (HREC) and/or institutional review boards prior to the establishment and inclusion into the LATAM-CPR. Ethical approval for LATAM-CPR has already been obtained from the HREC in the two countries that started (Argentina and Mexico). Findings will be disseminated and will be made publicly available through peer-reviewed publications, conference presentations and social media communications.

Evaluation of ALBA device for upper extremity motor function in adults with subacute and chronic acquired brain injury: a randomised controlled trial protocol in a tertiary clinic of the metropolitan region of Chile.

INTRODUCTION: Stroke is a significant worldwide cause of death and a prevalent contributor to long-term disability among adults. Survivors commonly encounter a wide array of motor, sensory and cognitive impairments. Rehabilitation interventions, mainly targeting the upper extremities, include a wide array of components, although the evidence indicates that the intensity of practice and task-specific training play crucial roles in facilitating effective results. Assisted therapy with electronic devices designed for the affected upper extremity could be employed to enable partial or total control of this limb, while simultaneously incorporating the aforementioned characteristics in the rehabilitation process. METHODS AND ANALYSIS: 32 adults who had a subacute or chronic stroke, aged over 18 years old, will be included for this randomised controlled trial aiming to determine the non-inferiority effect of the inclusion of a robotic device (ALBA) to regular treatment against only regular rehabilitation. Participants will be assessed before and after 4 weeks of intervention and at 3 months of follow-up. The primary outcome will be the Fugl-Meyer assessment for upper extremities; secondary outcomes will include the questionnaires Functional Independence Measure, Medical Outcomes Study 36-item Short-Form Health Survey as well as the System Usability Scale. ETHICS AND DISSEMINATION: Full ethical approval was obtained for this study from the scientific and ethical review board Servicio de Salud Metropolitano Oriente of Santiago (approval number: SSMOriente030522), and the recommendations of the Chilean law no 20120 of 7 September 2006, concerning scientific research in the human being, its genome and human cloning, will be followed. Ahead of inclusion, potential participants will read and sign a written informed consent form. Future findings will be presented and published in conferences and peer-reviewed journals. TRIAL REGISTRATION NUMBER: International ClinicalTrials.gov Registry (NCT05824416; https://clinicaltrials.gov/ct2/show/NCT05824416?term=uMOV&draw=2&rank=1).

Undernutrition risk is independently associated with worsened indicators of hospital rehabilitation in COVID-19 patients.

OBJECTIVE: This study was designed to analyze the association between the risk of undernutrition and indicators of hospital rehabilitation in patients with COVID-19 while controlling for confounding variables. METHODS: This was an analytical study conducted by analyzing the medical records of patients with COVID-19. A total of 562 adult patients were eligible for the study. In addition to the risk of undernutrition (independent variable), indicators of hospital rehabilitation (dependent variables) were evaluated. These indicators included the length of hospital stay, clinical outcome (discharge or death), food intake, mobility (bedridden status), the use of mechanical ventilation, and the need for enteral nutrition. Pre-existing comorbidities (confounding/control variables) were grouped into cardiovascular, metabolic/endocrine, neurological, chronic obstructive pulmonary disease, and other categories (neoplasms, multiple sclerosis, and kidney disease). A dichotomization model was applied for data analysis. The Chi-Square test was used to verify the association between the risk of undernutrition and the dependent variables. Associations with a significance level of P < 0.05 were subjected to Poisson regression to identify the prevalence ratio. RESULTS: Patients at risk of undernutrition had a 90% higher chance of being bedridden and were 35 times more likely to experience a decrease in food intake. They also had an 89% higher chance of using invasive mechanical ventilation and a 91% higher chance of requiring enteral nutrition. Additionally, individuals at risk of undernutrition had a 73% higher chance of death. Adjustment for comorbidities did not alter these associations, demonstrating that the risk of undernutrition is independently associated with indicators of hospital rehabilitation. CONCLUSION: The risk of undernutrition is independently associated with worsened indicators of hospital rehabilitation in patients with COVID-19, including higher prevalence of mortality.

NEUROCANTRIAL: study protocol for a randomised controlled trial of a pain neuroscience education programme in adults with cancer pain.

INTRODUCTION: Pain is the second most frequent symptom reported in patients with cancer among the main reasons for consultation. The incorporation of educational modalities in pain intervention processes has been suggested. This study aims to examine the efficacy of neuroscience pain education (PNE) in relation to pain, biopsychosocial variables and functional capacity in comparison with conventional treatment. It is hypothesised that an intervention based on PNE achieves better outcomes than conventional management, in terms of pain, biopsychosocial variables and functional capacity in adults with oncological pain. METHODS AND ANALYSIS: This will be a single-blind, controlled clinical trial in which two groups will be compared using changes in pain as the primary measure. The first group will receive conventional treatment in addition to PNE, and participants will undergo an intervention of nine sessions (one session per week, for a total of 9 weeks), each lasting 30-40 min. Specifically, these sessions will teach biophysiological elements using metaphors that allow the adoption of these concepts related to pain. The second group will receive conventional treatment (pharmacological treatment). For this study, a sample size calculation was made based on the background, where 80 adults with oncological pain were required. An initial evaluation will be made to establish the baseline characteristics, and then, according to the randomisation, the assignment to the PNE group or the control group will be made and the two groups will be summoned again. Ten weeks later, for the intervention evaluation, the statistical analysis plan will be established by protocol and by intention-to-treat. ETHICS AND DISSEMINATION: This protocol complies with all ethical considerations. The authors commit to presenting the study's results. This study was approved by the ethics committees of the Universidad Santiago de Cali, Clínica de Occidente/Angiografía de Occidente. The authors commit to presenting the study's results. TRIAL REGISTRATION NUMBER: NCT05581784.

Complex physical therapy employing self-adjusting garment (ReadyWrap®) in breast cancer-related lymphedema cases in Brazilian women: a protocol for a randomized controlled trial.

BACKGROUND: Lymphedema is a common complication following breast cancer treatment. The aim of this study is to evaluate the effectiveness of a self-adjusting compression garment (ReadyWrap®) in reducing (phase 1) and maintaining (phase 2) upper limb volume in women presenting breast cancer-related lymphedema. METHODS: This study will comprise a randomized, controlled, single-blind clinical trial concerning women with breast cancer-related lymphedema undergoing treatment at a public cancer treatment reference hospital in the city of Rio de Janeiro, Brazil. The intervention will be carried out by adapting self-dressing versus the standard treatment of compressive bandaging (phase 1) and compressive mesh (phase 2). Both groups will be assessed at the beginning and end of intensive treatment and followed up for up to 12 months to evaluate immediate and late outcomes. Assessments will be carried out by physical upper limb examination (inspection, palpation, volume, dynamometry, and thermography) and questionnaires application to assess patient's quality of life pertaining to the health, functionality, and symptoms of the affected upper limb, as well adverse effects and adherence to treatment. Data will be analyzed descriptively and analytically through univariate and multiple linear regressions. P values < 0.05 will be considered statistically significant. DISCUSSION: This study will evaluate the effectiveness of a self-adjustable garment (ReadyWrap®) in the treatment of lymphedema secondary to breast cancer in Brazilian women compared to the gold standard treatment for limb volume reduction (phase 1) and maintenance (phase 2) phases comprising, respectively, a compressive bandaging and a compressive mesh. The outcome results will provide data based on both quantitative responses and self-reported participant outcomes. The study will also assess the cost-effectiveness of the ReadyWrap® treatment versus standard care. Finally, we expect to reaffirm one more product/therapy as a treatment for this extremely complex and impactful condition following the data analysis.

Effectiveness of physical exercise programmes in reducing complications associated with secondary lymphoedema to breast cancer: a protocol for an overview of systematic reviews.

INTRODUCTION: Breast cancer-related lymphoedema (BCRL) is one of the most underestimated and debilitating complications associated with the treatment that women with breast cancer receive. Several systematic reviews (SRs) of different physical exercise programmes have been published, presenting disperse and contradictory clinical results. Therefore, there is a need for access to the best available and summarised evidence to capture and evaluate all the physical exercise programmes that focus on reducing BCRL. OBJECTIVE: To evaluate the effectiveness of different physical exercise programmes in reducing the volume of lymphoedema, pain intensity and improving quality of life. METHOD AND ANALYSIS: The protocol of this overview is reported following the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols, and its methodology is based on Cochrane Handbook for Systematic Reviews of Interventions. Only those SRs involving physical exercise by patients with BCRL will be included, whether on its own or combined with other exercises or other physical therapy interventions.The outcomes of interest to be considered will be lymphoedema volume, quality of life, pain intensity, grip strength, range of motion, upper limb function and any adverse event. The MEDLINE/PubMed, Lilacs, Cochrane Library, PEDro and Embase databases will be searched for reports published from database inception to April 2023.Two researchers will perform study selection, data extraction and risk of bias assessment independently. Any discrepancy will be resolved by consensus, or ultimately, by a third-party reviewer. We will use Grading of Recommendations Assessment, Development and Evaluation System to assess the overall quality of the body of evidence. ETHICS AND DISSEMINATION: The results of this overview will be published in peer-reviewed scholarly journals and the scientific dissemination will take place in national or international conferences. This study does not require approval from an ethics committee, as it does not directly collect information from patients. PROSPERO REGISTRATION NUMBER: CRD42022334433.

Assessment of redundancy, methodological and reporting quality, and potential discrepancies of results of systematic reviews of early mobilisation of critically ill adults: a meta-research protocol.

INTRODUCTION: Several systematic reviews (SRs) have been conducted to determine the effectiveness of early mobilisation in critically ill adults with heterogeneous methodology and results. Redundancy in conducting SRs, unclear justification when leading new SRs or updating, and discordant results of SRs on the same research question may generate research waste that makes it difficult for clinicians to keep up to date with the best available evidence. This meta-research aims to assess the redundancy, methodological and reporting quality, and potential reasons for discordance in the results reported by SRs conducted to determine the effectiveness of early mobilisation in critically ill adult patients. METHODS AND ANALYSIS: A meta-research of early mobilisation SRs in critically ill adult patients will be conducted. A search of MEDLINE (Ovid), Embase (Ovid), CINAHL (EBSCOhost), Cochrane Library, Epistemonikos and other search resources will be conducted. Two independent reviewers will perform study selection, data extraction and quality appraisal. Discrepancies will be resolved by consensus or a third reviewer. The redundancy of SRs will be assessed by the degree of overlap of primary studies. In addition, the justification for conducting new SRs will be evaluated with the 'Evidence-Based Research' framework. The methodological quality of the SRs will be assessed with the A MeaSurement Tool to Assess systematic Reviews 2 tool, and the quality of the reports through compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. To assess the potential reasons for discordance in the results of the SRs considering divergence in results and their interpretation. ETHICS AND DISSEMINATION: As meta-research, this study does not involve the participation of people whose rights may be violated. However, this overview will be developed rigorously and systematically to achieve valid and reliable results. The findings of this meta-research study will be presented at conferences and published in a peer-reviewed journal related to rehabilitation, critical care or research methodology.

Monitoring sarcopenia with wearable devices: a systematic review protocol.

INTRODUCTION: Sarcopenia is a highly prevalent muscle dysfunction among older adults and is associated with adverse events. The periodic monitoring enables an early screening of patients at risk and control of the progression of muscle impairment. Wearable devices have been used as clinical support for sarcopenia detection. Therefore, this review aims to identify how wearable devices have been used to screen sarcopenia. METHODS AND ANALYSES: Searches will be conducted from August 2023 on PubMed, CINHAL, Embase, Web of Science and SciELO databases. We will include cross-sectional and/or baseline data from prospective studies reporting the use of wearable devices to investigate sarcopenia. Studies that discuss only the development of algorithms or applications for the assessment of sarcopenia or unavailable full texts will be excluded. The main reviewer will conduct the initial search and exclusion of duplicates, while two independent reviewers will select studies, extract data and assess the methodological quality using the Appraisal tool for Cross-sectional Studies. ETHICS AND DISSEMINATION: No previous ethical approval is required for this review. The findings of this review will be submitted to a scientific journal and disclosed at international scientific conferences. PROSPERO REGISTRATION NUMBER: CRD42022356040.

Physical performance testing in post-COVID-19 patients: protocol for a systematic review of psychometric measurement properties.

INTRODUCTION: COVID-19 is an infectious disease that causes severe acute respiratory syndrome. A large variety of exercise capacity tests are used for the evaluation of post-COVID-19 patients, but the psychometric properties of these exercise tests remain undetermined in this population. This study aims to critically appraise, compare and summarise the psychometric properties (validity, reliability and responsiveness) of all physical performance tests that are used to assess exercise capacity in post-COVID-19 patients. METHODS AND ANALYSIS: This systematic review protocol follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols guidelines. We will include studies with hospitalised adult post-COVID-19 patients (aged 18 years or older and with a confirmed diagnosis of COVID-19). The research will cover randomised controlled trials (RCTs), quasi-RCTs and observational studies published in English and performed in the following settings: hospital, rehabilitation centre, outpatient clinic. We will search the following databases with no date restrictions: PubMed/MEDLINE, EMBASE, SciELO, Cochrane Library, CINAHL and Web of Science. Two authors will independently assess the risk of bias (using the Consensus-Based Standards for the Selection of Health Measurement Instruments Risk of bias checklist) and the certainty of evidence (using the Grading of Recommendations, Assessment, Development and Evaluations). According to the results obtained, data will be meta-analysed or reported narratively. ETHICS AND DISSEMINATION: No ethical approval is required for this publication since it will be based on published data. Results of this review will be disseminated via peer-reviewed publications and conference presentations. PROSPERO REGISTRATION NUMBER: CRD42021242334.

Investigating the hypoalgesic effects of spinal manipulative therapy using hidden pain conditioning and positive expectation in patients with chronic low back pain: protocol for a randomised controlled trial.

INTRODUCTION: Placebo effects are responses capable of modulating pain and influencing treatment response. Two mechanisms are commonly related to placebo effects: expectations and conditioning. However, the research in this field is focused on laboratory studies with healthy participants. This study aims to identify whether a conditioning procedure with positive induced expectations about spinal manipulative therapy (SMT) will result in greater hypoalgesic effects in adults with chronic low back pain (CLBP) in a clinical trial design. METHODS AND ANALYSIS: This trial will enrol 264 patients with non-specific CLBP, aged 18-60 years. Patients will undergo a calibration test to determine the thermal pain threshold for the hidden pain conditioning procedure. Afterward, they will be randomised to one of the three groups: hidden pain conditioning with positive induced expectations-group one (G1); positive expectations-group two (G2) and neutral expectations-group three (G3). Patients will receive instructions to manipulate the expectations. The pretreatment heat pain test will be performed before the SMT and after the intervention patients will undergo again the heat pain intensity test. However, only patients in G1 will receive hidden pain conditioning to reinforce the association between SMT and pain intensity reduction. All patients will undergo five sessions of SMT. The outcomes will be assessed immediately after the last session and at the 6 weeks and 3-month follow-ups. All statistical analyses will be conducted following intention-to-treat principles, and the treatment effects will be determined with linear mixed models. ETHICS AND DISSEMINATION: The Federal University of São Carlos approved this research (Process n° 52359521.1.0000.5504). All participants will give written informed consent. Dissemination of the results will include publications in peer-reviewed journals and presentations at conferences. If positive expectations and classical conditioning improve outcomes, it may support the administration of such intervention. TRIAL REGISTRATION NUMBER: NCT05202704.

Effects of home healthcare for adults with chronic respiratory diseases and post-COVID-19 syndrome on hospital bed turnover rate: a protocol of systematic review with meta-analysis.

INTRODUCTION: Chronic respiratory diseases (CRDs) have a high prevalence, morbidity and mortality worldwide. After the COVID-19 pandemic, the number of patients readmitted after hospital discharge increased. For some populations, early hospital discharge and home healthcare may reduce health costs in patients treated at home when compared with those hospitalised. This study aims to systematically review the effectiveness of home healthcare for patients with CRDs and post-COVID-19 syndrome. METHODS AND ANALYSIS: We will search on MEDLINE, CENTRAL, Embase and PsycINFO. We will include randomised controlled trials (RCTs) and non-RCT studies reported in full text and abstracts. No language restriction will be applied. We will include studies related to adults with a diagnosis of CRDs or post-COVID-19 syndrome that compared in-patient hospital care with any home healthcare. We will exclude studies with participants with neurological, mental diseases, cancer or pregnant women. Two review authors will screen abstracts and select the eligible studies. To investigate the risk of bias, we will use the Cochrane 'Risk of Bias' tool for RCT, and the Risk of Bias In Non-randomised Studies-of Interventions for non-RCT. We will use the five Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) considerations to assess the quality of the evidence. Patients and the public will be involved in the preparation, execution and implementation phases of the review. ETHICS AND DISSEMINATION: No ethical approval is required because only published data will be analysed. The publication of the results in peer-reviewed journals and at relevant conferences will guide the direction of future research in the field and healthcare practice. The results will also be disseminated in plain language on social media to disseminate the knowledge to society and the public interested in the topic.

Usability of exergames as a home-based balance training tool for older adults: protocol for a systematic review.

INTRODUCTION: Exergames are used in the clinical practice of geriatric rehabilitation to increase physical activity levels and motivate players/patients. Their use in the home environment makes it possible to perform fun, engaging and interactive training with a large number of repetitions, thereby reducing the negative repercussions of postural imbalance in older adults. The aim of this systematic review is to collate and analyse evidence on the usability of exergames as a tool for home-based balance training for older adults. METHODS AND ANALYSIS: We will include randomised controlled trials involving healthy older adults (aged 60 years or older) who are described as having impaired static or dynamic balance using any subjective or objective assessment criteria. We will search Web of Science, MEDLINE, Embase, Scopus, ScienceDirect and the Cochrane Library from database inception to December 2022. CLINICALTRIALS: gov, the WHO International Clinical Trials Registry Platform and ReBEC will be searched for ongoing or unpublished trials. Two independent reviewers will screen the studies and extract the data. The findings will be presented in the text and tables, and if possible, relevant meta-analyses will be performed. The risk of bias and the quality of evidence will be assessed based on the recommendations of the Cochrane Handbook and Grading of Recommendations, Assessment, Development and Evaluation, respectively. ETHICS AND DISSEMINATION: Ethical approval was not required because of the nature of this study. Findings will be disseminated through peer-reviewed publications, conference presentations and through clinical rehabilitation networks. PROSPERO REGISTRATION NUMBER: CRD42022343290.

Strategies used to manage overlap of primary study data by exercise-related overviews: protocol for a systematic methodological review.

INTRODUCTION: One of the most conflicting methodological issues when conducting an overview is the overlap of primary studies across systematic reviews (SRs). Overlap in the pooled effect estimates across SRs may lead to overly precise effect estimates in the overview. SRs that focus on exercise-related interventions are often included in overviews aimed at grouping and determining the effectiveness of various interventions for managing specific health conditions. The aim of this systematic methodological review is to describe the strategies used by authors of overviews focusing on exercise-related interventions to manage the overlap of primary studies. METHODS AND ANALYSIS: A comprehensive search strategy has been developed for different databases and their platforms. The databases to be consulted will be MEDLINE (Ovid), Embase (Ovid), The Cochrane Database of Systematic Reviews (Cochrane Library) and Epistemonikos. Two reviewers will independently screen the records identified through the search strategy and extract the information from the included overviews. The frequency and the type of overlap management strategies of the primary studies included in the SRs will be considered as the main outcome. In addition, the recognition of the lack of use of any overlap management strategy and the congruence between planning and conducting the overview focusing on overlap management strategies will be assessed. A subgroup analysis will be carried out according to the journal impact factor, year of publication and compliance with the Preferred Reporting Items for Overviews of Reviews statement. ETHICS AND DISSEMINATION: This study will not involve human subjects and therefore does not require ethics committee approval. However, the conduct and reporting of the findings of this review will be conducted in a rigorous, systematic and transparent manner, which relates to research ethics.The findings of this review will be presented at scientific conferences and published as one or more studies in peer-review scientific journals related to rehabilitation or research methods.

Effects of intradialytic inspiratory muscle training at different intensities on diaphragm thickness and functional capacity: clinical trial protocol in patients undergoing haemodialysis.

INTRODUCTION: Patients with end-stage renal disease (ESRD) undergoing haemodialysis (HD) commonly present with a sedentary behaviour and reduced functional capacity, factors that can compromise their prognosis. Intradialytic inspiratory muscle training (IMT) can increase respiratory muscle strength and, consequently, improve functional capacity, besides being easy to apply, cheap and performed in a supervised setting. However, few studies show the effects of this type of training applied at different intensities in this population. This study aims to compare the effects of IMT at different intensities in adults with ESRD undergoing HD. METHODS AND ANALYSIS: A randomised, double-blind, sham-controlled trial will be conducted on 36 subjects randomly allocated into three groups: IMT at intensities of 30% or 50% of maximal inspiratory pressure (intervention groups), or 10% of maximal inspiratory pressure (sham-IMT). All the interventions will be supervised and performed three times per week, for 12 weeks, totalling 36 sessions.

Physical rehabilitation for the management of cancer-related fatigue during cytotoxic treatment: a systematic review with meta-analysis.

OBJECTIVE: To assess the effect of physical therapy on cancer-related fatigue (CRF) during cytotoxic anticancer treatment. METHODS: Systematic review with meta-analysis of randomized clinical trials published from 2010 to 2021 (EMBASE, MEDLINE, PEDro; SciELO, and LILACS). Studies assessing the effect of supervised physical therapy (IG) for the management of CRF on adults undergoing anticancer treatment compared with a control group (CG) covering usual care or any uncontrolled practice, such as recommendations about exercise and health education, were included in this review. RESULTS: A total of 22 studies were included in the SR and 21 in the meta-analysis, resulting in 1.992 individuals (CG = 973 and IG = 1.019). There was a reduction in general fatigue [SMD = - 0.69; 95%CI (- 1.15, - 0.22) p < 0.01; I2 = 87%; NNT = 3], with greater weight attributed to combined exercise (44%). Physical fatigue also reduced [SMD = - 0.76; 95%CI (- 1.13, - 0.39) p < 0.01; I2 = 90%; NNT = 2], with greater weight for resistance exercise (50%) and greater effect with combined exercise [SMD = - 1.90; 95%CI (- 3.04, - 0.76) p < 0.01; I 2 = 96%]. There was reduction in general fatigue with moderate intensity (74%) [SMD = - 0.89; 95%CI (- 1.61, - 0.17) p < 0.02; I2 = 90%] and physical fatigue [SMD = - 1.00; 95%CI (- 1.54, - 0.46) p < 0.01; I2 = 92%], while high intensity reduced only general fatigue [SMD = - 0.35; 95%CI (- 0.51, - 0.20) p < 0.01; I2 = 0%]. The number of overall and weekly sessions has been shown to contribute to the reduction of CRF. CONCLUSION: Physical rehabilitation with moderate intensity promoted greater relief of general and physical fatigue. Even after controlling for high heterogeneity, the quality of evidence, summarized in GRADE, was considered moderate for general fatigue and low for physical fatigue.

Aquatic sports rehabilitation on functional recovery of knee joint injury / Reabilitação esportiva aquática na recuperação funcional de lesão do joelho / Rehabilitación deportiva acuática en la recuperación funcional de lesión de la rodilla

ABSTRACT Introduction Knee joint injury is a common sports injury and how to speed up the recovery process is a concern for all athletes. Objective Determine whether aquatic sports rehabilitation nursing can accelerate the rehabilitation process of knee joint injuries. Methods Thirty patients with knee ligament or meniscal injury were divided into an aquatic sports group and a control group. The control group assumed general recovery measures, while the aquatic exercise group was added another 8 weeks of rehabilitation nursing with aquatic exercises. The evolution of the degree of knee joint pain, knee joint range of motion, knee joint muscle strength and other indicators before and after the experiment were compared. Results After 8 weeks of intervention, pain and activities of daily living in the aquatic exercise group improved significantly compared with those before the experiment; the degree of recovery from knee joint injury in the aquatic exercise group was significantly better than that in the control group, and knee joint flexion range of motion, flexor and extensor muscle strength, and other indicators in the aquatic exercise group were significantly better than those in the control group. Conclusion Aquatic rehabilitation exercise can accelerate the recovery process of patients with knee joint injuries. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

RESUMO Introdução A lesão articular do joelho é uma lesão esportiva corriqueira e a maneira de acelerar o processo de recuperação é uma preocupação para todos os atletas. Objetivo Determinar se a enfermagem de reabilitação esportiva aquática pode acelerar o processo de reabilitação das lesões nas articulações do joelho. Métodos Trinta pacientes com lesão ligamentar ou meniscal do joelho foram divididos em grupo de esportes aquáticos e grupo de controle. O grupo de controle assumiu medidas gerais de recuperação, enquanto ao grupo de exercícios aquáticos acrescentou-se mais 8 semanas de enfermagem de reabilitação com exercícios aquáticos. Comparou-se a evolução do grau de dor na articulação do joelho, a amplitude de movimento da articulação do joelho, a força muscular da articulação do joelho e outros indicadores antes e depois da experiência. Resultados Após 8 semanas de intervenção, a dor e as atividades das atividades de vida diária no grupo de exercícios aquáticos melhoraram significativamente em comparação com aquelas antes do experimento; o grau de recuperação da lesão da articulação do joelho no grupo de exercícios aquáticos foi significativamente melhor do que o do grupo controle, e a amplitude de flexão da articulação do joelho, a força muscular flexora e extensora e outros indicadores no grupo de exercícios aquáticos foram significativamente melhores do que os do grupo controle. Conclusão O exercício de reabilitação aquática pode acelerar o processo de recuperação de pacientes com lesões articulares no joelho. Nível de evidência II; Estudos terapêuticos - investigação dos resultados do tratamento.
